New Release: Tor Browser 8.5a4

Highlights in Tor Browser 8.5a4 are a new Tor alpha version, 0.3.5.3-alpha, a fixed layout of our macOS installer window and Stylo (Mozilla's new CSS engine) being enabled on macOS after fixing a reproducibility issues. Please report any problems you find with those macOS related changes as we think about backporting them for the stable series.

Moreover, we backport a defense against protocol handler enumeration developed by Mozilla engineers and provide Tor Browser on all supported platforms in four additional locales: cs, el, hu, and ka.

Note: It turned out it was a bit premature to ship the new locales as we did not catch bugs in them last minute, so we don't make them available on our download page. Sorry for the inconvenience.

Well, requests for cached items should not hit the network. Thus, that might be a misleading log line in that the request is later on cancelled internally (i.e. the resource gets loaded from the cache but the request is not going out over the network).

Hello, I've said this on every update post since the 'Quantum' upgrade:
- Tor doesn't remember the size that it was left on before closing, so when it opens again it ends up being in a very specific and unique size for those of us that have tabs open.
- Tor is not allowing me to login to disqus, no matter what I add to the whitelist.
- Can you bring back the Sync function?

I've tried to fix those issues on Windows 7, Ubuntu 16.04, Ubuntu 18 and Windows Vista with no success.

What size is that for you? Can you check with some test on the internet? Regarding Disqus: yes, that's a known but someone needs to investigate: https://trac.torproject.org/projects/tor/ticket/27249 (please help if you can). Finally, Sync is just disabled via identity.fxaccounts.enabled set to false, I believe. Does flipping that pref help you?

"we are adding a notification to our Firefox Quantum browser that alerts desktop users when they visit a site that has had a recently reported data breach. We’re bringing this functionality to Firefox users in recognition of the growing interest in these types of privacy- and security-centric features."

2 months and Tor 8.0-8.5 wont start without displaying anything. The voluntarily turned on log shows:
"Error: the firefox package (version 60 or more) is not installed.
On CentOS/RHEL 6, Tor Browser requires the firefox package to be installed."
Always downgrading to v7 by overwriting directory contents, and that works.

NoScript is still not saving per site permissions. This is seriously annoying, preventing me from customizing which sites I trust or not, while turning script fully on by default, every time Tor Browser is restarted! As it's been several iterations now since this bug has been active, I'm going right back to an older version of Tor Browser until it's fixed.
